Answer:
[tex]M_{diluted}=0.35M[/tex]
Explanation:
Hello,
In this case, since in a dilution process the moles of the solute must remain unchanged, we use the volumes and molarities as shown below:
[tex]M_{diluted}V_{diluted}=M_{concentrated}V_{concentrated}[/tex]
Clearly, the concentrated solution is 7.00M and the diluted solution is unknown, thus, the concentration of the diluted solution after the dilution to 100 mL is:
[tex]M_{diluted}=\frac{M_{concentrated}V_{concentrated}}{V_{diluted}} =\frac{7.00M*5.00mL}{100mL}\\ \\M_{diluted}=0.35M[/tex]
Best regards.
